Troubleshooting

Problem	Solution
No Power	Ensure the AAA battery is inserted correctly with the correct polarity. Replace the battery with a fresh one.
Poor Reception (FM)	Extend the headphone cord fully, as it acts as the FM antenna. Try adjusting the FM Local/DX switch. Move to a location with better signal reception.
Poor Reception (AM/WB)	Rotate the unit for optimal reception, as the AM/WB antenna is built-in. Move away from electronic devices that may cause interference.
Clock not displaying correctly	Re-set the digital clock following the instructions in the "Operating Instructions" section. Check battery level; low battery can affect clock function.
